πToday Tip
π«1. What is bearing capacity of soil?
βΊThe maximum load per unit area that the soil or rock can safely carry without shear failure or excessive settlement. Itβs crucial for foundation design! ποΈπ
π«2. Define workability!
βΊWorkability is the ease with which concrete can be mixed, transported, placed, compacted, and finished without segregation. Think smooth handling! π€οΈπ§
π«3. What is Grade of Concrete?
βΊThe grade indicates the compressive strength of concrete after 28 days, like C-20 (20 MPa). Higher grade = stronger concrete! π₯π§±
π«4. What is water cement ratio in concrete?
βΊItβs the ratio of water weight to cement weight in the mix (e.g., 0.45). Lower ratio means higher strength but less workability! π§ποΈ
π«5. What is density of water?
βΊ1000 kg/mΒ³ (or 1 g/cmΒ³) at standard temperature. The gold standard for concrete calculations! ππ
π«6. Buckling of sand?
βΊ(I think you mean Bulking of sand! π) Bulking is the sudden increase in sand volume (up to 20-30%) when moist due to air voids between particles. Always account for it in mixes! ποΈπ
π«7. Define Bending Moment and Shear force?
βΊBending Moment: The internal moment that causes a beam to bend (like twisting force).
βΊShear Force: The vertical force that tends to shear (cut) the beam cross-section. Key for structural analysis! πβοΈ
π«8. Types of staircase?
β¦ Straight flight πββοΈ
β¦ L-shaped (quarter turn) β©οΈ
β¦ U-shaped (half turn) βͺοΈ
β¦ Spiral (curved) π
β¦ Winder (space-saving) π
π²Choose based on space and aesthetics! ποΈ
π«9. What is Bond?
βΊIn RCC, bond is the adhesion between concrete and reinforcement bars (steel), ensuring they act as one unit under load. Strong bond = no slips! ππ‘οΈ
π«10. What is foundation and Types of Foundation?
βΊFoundation transfers structure load to the ground safely.
π§Types:
β¦ Shallow: Strip footing (for walls), Pad/isolated (for columns), Raft/mat (for large areas).
β¦ Deep: Pile (for weak soil), Caisson (for waterlogged areas). Pick wisely! βπ±
π«11. What is bleeding and segregation in concrete?
βΊBleeding: Excess water rising to the surface during compaction (like sweating concrete).
βΊSegregation: Separation of aggregates from cement paste, leading to weak mix. Avoid by proper mixing! π«π¦
π«12. What is the Minimum curing for slab?
βΊMinimum 7 days for basic strength, but ideally 14-28 days for full hydration and durability. Keep it moist! π§οΈπ
π«13. What formwork and also defined shutting?
βΊFormwork: Temporary molds (wood, steel, etc.) to shape fresh concrete until it hardens.
βΊShuttering: Specifically the vertical part of formwork (sides) that holds the concrete in place. Essential for clean finishes! π οΈπ¦
π«14. What is Mix design concrete?
βΊThe scientific process to find the optimal proportions of cement, water, aggregates, and admixtures for desired strength, workability, and durability. Tailor-made for every project! π§ͺποΈ
π«15. What are the Types of Concrete?
β¦ Normal/Ordinary Portland π§
β¦ High-strength (HSC) ποΈββοΈ
β¦ Lightweight (for insulation) βοΈ
β¦ Heavyweight (for radiation shielding) β‘
β¦ Self-compacting (flows on its own) π
β¦ And more like fiber-reinforced or precast!
